* Sarissa comes from an old Hebrew word, which is the same word that Sarah derives from (and in fact, Harry accidentally calls Sarissa Sarah when he's trying to remember her name.) The brilliance? The same word is also the Hebrew word for [[spoiler:"princess." As in, "Daughter of a queen."]] It's also a weapon (a type of spear).
* Sarissa's actions at Harry's birthday party: Of ''course'' the only Changeling brave/confident enough to bring iron into Arctis Tor is [[spoiler: Mab's daughter]].
* Two of Mother Winter's names are Skuld (a Norn) and Atropos, one of the three sisters. It is also stated that there is a name that both the Mothers share that is even more powerful. Given the domains of the first two names, the third is most likely [[spoiler:Fate]]. When you realize that in the original myths the creatures of Winter and Summer are not different individuals on opposite sides, but the same person at different times [[spoiler:much like Kringle and Odin,]] the Mothers' conversation makes a bit more sense, kind of a "what once was split be made whole" kinda thing.
* Going into Horror, when one thinks about what if Harry had used [[spoiler:Fates']] name. It's a good chance that instead of one of the Mothers he would have gotten the one and only [[MotherEarth Mother]]. Honestly, if Mother Winter is [[spoiler:Fate]], then the idea that Mother Summer is also MotherEarth makes a lot of sense.
* Kringle is the expert on [[spoiler: temporal manipulation.]] Which makes sense when you think that [[spoiler: Santa would need a lot more time than one night to get all around the world.]]
* Kringle riding with TheWildHunt makes a lot more sense if you know that [[spoiler:he's Odin, who commands the Hunt in mythology.]]
* YMMV on whether this is brilliance or horror. [[spoiler:Kringle is Odin, which means that the face of Christmas, the largest Christian holiday, is a pagan god (though Kringle admits "Santa Claus" is both recent and primarily secular). It also works in the real world as Odin is a candidate for the original myth of Santa Claus]].
* Erlking and Kringle are anagrams of one another.
* Going off the anagram mention, it stands to reason that when Kringle [[spoiler:took the "Santa Clause"-Mask,]] Erlking took [[spoiler:the "Krampus"-mask and went after naughty children.]]
* On Odin's source of power. Backup shows that a lot of the beings in the Dresdenverse depend on belief (or at least a large number of people knowing about the being in question), almost certainly including gods of various calibre. Since the worship of Odin is not nearly as big now as it was in the Viking heyday, how does he have all the juice to fight vampire gods and raise Norse heroes from the dead? [[spoiler: Who believes in Father Christmas?]] Which might explain why the Erlking has a reputation for [[spoiler: being a protector of children, despite his ferocity]]. He's been looking out for his hunting-buddy's best interests!
* With respect to ''Proven Guilty''. At the time, it appeared that Molly was taken to Arctis Tor as punishment for interfering with Winter's plans. But this was also when Molly was most likely to be executed by the White Council. She was kidnapped so that she would survive long enough for Dresden to become her protector. And Dresden became aware of her potential as a result of being told about black magic by ... The Gatekeeper. Who it turns out shares defense duty with Winter at the Outer Gates.
* Alternatively, remember how "all of Winter" was after Harry in ''Proven Guilty''? Now consider that most of those faeries were supposed to be guarding [[spoiler: the Outer Gates]]. Also remember that this was at least partly Maeve's idea - and she was already saying that Mab was insane and [[spoiler:therefore must have already been infected by Nemesis]]. And then Michael mentions there were Outsiders involved in the Red Court attack on the Warden training camp. It looks like the entire thing - Molly's kidnapping, the rescue mission, everything - [[spoiler:was a diversion orchestrated by Maeve to get Outsiders into reality.]] NiceJobBreakingItHero. [[spoiler: Although it ''was'' Lea's Nemesis-infected side that said "all of Winter" was coming - that "crazy gleam" in her eyes was a hint to that effect - so she may have been lying about that.]]
* Both Mab and Harry spend the book having daughter issues. Specifically, having a daughter that they, in their own ways, love and want to help, but because of duty can't either be with ([[spoiler:Maeve]]) or help ([[spoiler:Sarissa]]). [[spoiler:It ends badly for Mab. One dies, and the other is taken by Summer forever. A possible foreshadowing of Harry's own relationship with Maggie?]]
* A meta one: Butcher gives the weight that Dresden can press in both kilos and stones. The European fanbase approves, because we get length in feet and inches often enough to know what it is in meters - but weights are something completely different. This way, everybody understands just how ridiculously strong Dresden has become.
* Harry, who has consistently been OneOfUs (in terms of his obsession with comic books, sci-fi and fantasy) [[PopculturalOsmosisFailure has no idea what Bob is talking about]] when he mentions the [[Series/{{Firefly}} "special hell" for people who talk during a movie]]. Because since Harry's power makes him a WalkingTechbane, he probably hasn't watched television since the Nineties (judging by his [[Series/BuffyTheVampireSlayer Buffy]] references), and thus never watched Firefly.
* So how did thousands of [[EldritchAbomination Eldritch Abominations]] get trapped in Demonreach? Well, that's what the giant uber-circle and the Warden are for. The Warden summons some unspeakable horror inside of the perfect, unbreakable trap and lets the island clap it in irons for him.
* Waaaay back in ''Storm Front'', Harry encounters a Three-Eye junkie at the police station, who raves about how "those who walk before and He Who Walks Behind" are coming for the wizard. At the time, Harry's floored that the addict could See the mark of the Walker he'd confronted as a teenager on him. But now, it seems the junkie might actually have Seen ''Harry's future'' as well, because [[spoiler: "those who walk before" might actually have been a reference to Sharkface -- aka He Who Walks Before -- and his power of SelfDuplication]]. Sells' potion/drugs may have been more potent than Harry ever suspected.
* On a meta level, the reason [[spoiler:Molly]] was able to become the Winter Lady conforms perfectly with [[AsskickingEqualsAuthority Winter philosophy]]. During ''Changes'', both she and Harry suffered trauma from killing the person they loved. The difference is that Harry could not bear the pain of this (and killed himself) where Molly endured her guilt and survived, making it possible for Lea to train her. In a culture that values strength highly, it makes sense that she would be ranked higher than him.
* According to WordOfGod, [[spoiler:Justin DuMorne was collecting the Starborn to raise them into a weapon to destroy Outsiders]]. So... does that mean [[spoiler:Elaine Mallory is ''also'' a Starborn Outsider-killer]]?
* At the birthday party, Mab and Harry dance to ''Shinedown'''s "45". The song's lyrical version describes an [[spoiler:"unborn child" who will be given life]]. And in the very next book, [[spoiler:Harry gives birth to a spirit- who was gestating in his head]] during ''Cold Days''.
* The revelation that [[spoiler: Odin is also Santa]] makes Vaderrung's all-steel office decor more significant. [[spoiler: In his Santa aspect, he's presumably susceptible to the limits and obligations of a faerie, albeit a very powerful one. An all-steel environment that's baneful to the fey may help him to keep his Norse-deity-turned-CEO aspect fully compartmentalized from his faerie aspect, freeing him to act outside Winter Law or Wyldfae custom, as well as limiting the Queens' ability to snoop at what he's doing in his office.]]

* At the end, [[spoiler: Mab]] tries to make the events of the climax less horrific to Harry by explaining that she had intended for [[spoiler: Molly to become the Summer Lady, but things didn't quite work out.]] But considering Titania's reaction to meeting with Harry, and Lily's more especially, and knowing what we know about [[spoiler: Molly's]] character, isn't it even creepier to think of her being considered as the prime candidate for a position whose ''job description literally includes poor emotional control''? Possible FridgeBrilliance: perhaps that is ''why'' [[spoiler:Mab]] considered [[spoiler: Molly]] a better fit for Summer. Mitigating this would be the fact [[spoiler:Mab didn't intend for it, but merely knew it was a high chance of happening and had several plans in motion. Note, had Harry just summoned Mab when he arrived inside the circle, things could have happened differently.]]
* Blink and you'll miss it, but Harry mentions four "famous" historical figures that had held the mantle of the Winter Knight before Lloyd Slate: Gilles de Rais, Fritz Haarmann, John Haigh, and [[Film/CitizenX Andrei Chikatilo]]. All of them were executed as serial killers, and three of those four were known to prey on children. Given the similarities in those cases, and the repeated statements from various parties that the Winter Knight's mantle alters its holder's personality to conform to its archetype ... it's tough to blame Sarissa, or Fix, or Harry's friends, or Harry himself for being scared.
* Throughout the novel, Harry takes great pains to try to keep his friends and family out of the brewing conflict with the Sidhe, since involvement in his affairs makes anyone fair game. [[spoiler: He utterly fails. Everyone's involvement is known -- Butters, Andi, Mac, and Justine all catch hits for it despite being only briefly involved with supporting him.]] Those people? Got off light. [[spoiler: Thomas was an active fighter in the whole affair, and Molly is now Winter Lady.]] They can at least take care of themselves on some level, though. [[spoiler: Karrin killed Maeve, Mab's daughter, by shooting her in the face. Worse, the person likeliest to take revenge isn't Mab -- it's Redcap, Maeve's lieutenant and the fairy equivalent of a SerialKiller.]]
* Harry spends the entire novel lacking the nerve to visit his daughter, and never works himself up to where he dares go to the Carpenters' place and come inside. He's afraid she might remember the events at Chichen Itza, and how he'd killed Susan on the Red King's sacrificial altar. By the end of the novel, Harry has ''just started'' to embrace the notion that he needs to re-integrate with his friends again, a process which one would ''think'' would culminate in him finally meeting Maggie ... except [[spoiler: now that Molly has been forced to become the Winter Lady on Harry's watch, he probably won't have the nerve to visit the Carpenters for fear of how Michael and Charity will react to ''that''!]]
* Speaking of the Carpenters, how will any of them react to the news that [[spoiler: Molly has become a faerie Queen]]? Does this mean [[spoiler: her soul will spend eternity in Faerie and can never go to Heaven]]?
* At first, it seems like for all the bad things that would happen if Demonreach exploded, killing millions of people and wiping out a good portion of the United States, we could have taken some comfort that the explosion would have happened on Halloween Night. The time when all of those horrible immortal nasties are mortal, and can actually be killed. It is likely that the ritual to destroy Demonreach was originally created by Merlin, or someone working with him, and specifically designed to be cast only on Halloween night, specifically for this purpose. What makes this horror instead of brilliance is that the setup of the attack as described by Demonreach and elaborated by Odin. The attack spell was set up through space and time. Harry stopped the ritual on Halloween night, but if he hadn't, the spell would have hit and the island gone critical the following morning. Arguably, that's even better for Nemesis if it could trick the ritual into starting, setting up the prison breaking open, and then fudging things so that the explosion happened at a time when the prisoners could not be killed.
* [[spoiler: NiceGirl Lily]] attempting to kill Harry is already NightmareFuel but also raises some horrific implications. [[spoiler: First, she blames Harry for her current situation, saying that by killing Aurora making her Summer Lady, he stole her chance for a normal life, which makes one wonder if she only came to this conclusion recently when Meave was manipulating her or was this resentment something she ''always'' had towards Harry, starting from the end of Summer Knight. Then there's Lily summoning a mountain to charbroil Harry ''while he's holding Fix's body'' meaning Lily was so fixated on revenge that she didnt care about ''burning her best friend alive or desecrating his corpse.'' Finally, there's Fix and Lily's reactions afterwards once she cools down when its revealed he's alive and ok. Fix tells her to calm down and do her usual meditations, and doesn't seem scared, shocked or horrified at his friend's behavior and near murder of him, implying that this isn't the ''first'' time Lily's gone on a rampage like this and given Titania's earlier rage against Harry such tantrums may be ''normal.'' Meanwhile, Lily finds out she almost killed her friend but rather than sit down and digest it or show remorse, she ''immediately goes back to breaking the island's seal'' showing where her priorities lie.]]
* Molly submits to the Winter Knight's urges, which is made even more disturbing by her past captivity in Arctis Tor. She ''knows'' how brutal Winter can be, and serves it anyway.
